Answer:

1.) Liquid

2.) Low

3.) Molecular

4.) Surface tension

5.) Solvent

Explanation:

Water is important to living things because it remains in the LIQUID state over a wide range of temperatures. Water in lakes and oceans does

not experience large temperature changes because liquid water has a

LOW specific heat, so it must absorb or release a lot of energy as its temperature changes. The MOLECULAR forces between water

molecules cause water to form round droplets and cause water's high SURFACE TENSION. Water is also an important SOLVENT because it can

dissolve many different substances.

IP Force to Hold a Baseball A person holds a 1.42-N baseball in his hand, a distance of 34.0 cm from the elbow joint, as shown i

mixer [17]

We will assume that the CM of the arm is at "L" from the elbow, and the ball is at 34cm. Then the net torque is computed by:

Net τ = 1.42 N * 34 cm + 1.50 kg * 9.8m/s² * 34 cm/2 – 12.6 N*2.75cm

= 48.28 N*cm + 1.50kg * 9.8m/s² * 34 cm/2 – 12.6 N*2.75cm

= 48.28 N*cm + 499.8 – 34.65 N*cm

τ = 513.43 N*cm or 5.1343 N*m

A Thomson's gazelle can run at very high speeds, but its acceleration is relatively modest. A reasonable model for the sprint of

777dan777 [17]

Answer:

The correct answer will be:

(a) 27.3 m/s

(b) 3.8 s

Explanation:

According to the question:

Acceleration,

$a= 4.2 \ m/s^2$

Time,

$t = 6.5 \ s$

(a)

The gazelles top speed will be:

⇒ $V_{max} = at$

$=4.2\times 6.5$

$=27.3 \ m/s$

or,

$= 27 \ m/s$

(b)

As we know,

s = 30 m

Now,

⇒ $s = \frac{1}{2} at^2$

or,

⇒ $t=\sqrt{\frac{2s}{a} }$

On putting the given values, we get

$=\sqrt{\frac{2\times 30}{4.2} }$

$=\sqrt{\frac{60}{4.2} }$

$=3.78 \ s$

or,

$=3.8 \ s$
